Transcript Non Mendelan Genetics Foldable

Non Mendelan Genetics Foldable
Fold your paper so you have 2 flaps
opposite each other

Next cut four divisions on each side. You should
have a total of 8, four on each side.

Label the left side: CoDominance, Incomplete
dominance, Polygenetic, Gametes,
Label the first 2 flaps on the right side: Multiple
alleles, label the 3rd flap autosomes and the 4th flap
Sex linked

Incomplete Dominance
–
–
On the first flap write:
Heterozygous phenotype is halfway in between
the two homozygous phenotypes
Red flower x white flower = pink flower!!!
 RR X WW = RW
Cut out the picture Color the flowers according to the key
above and glue down under flap

Codominance

Under the codominance flap write:
–
Both alleles contribute to phenotype



Normal blood cells x Sickle blood cells = both normal
and sickle cell blood.
In this case it would be a positive change. People who
are carriers for sickle cell disease are protected against
Malaria!
Find the sickle cell picture color it and glue it under the
codominance flap.
Multiple Alleles

Under the first flap write:
–
Many genes have MORE than two alleles




Rabbit coat color (C, c, cch, ch)
Human blood type (A, B, O)
Blood type is written with the letter I to represent A and
B which are codominate and i to represent O which is
resessive.
Find the blood type picture and color each row a
different color then glue it down under your multiple
allele flap.
Polygenic Traits
Under the polygenic flap write
Traits produced by interaction of more than one
gene



Human skin color and height
Always makes a bell shaped curve.
Find the picture of polygenic traits, draw in the bell
shaped curve and glue it down under your flap
Gametes





Write the following under the gamete flap
Gametes are sex cells, they have ½ the number of
chromosomes as autosomes (23 instead of 46)
Male gamete –sperm
Female gamete – egg
The gene for sex if on the Y chromosome so the Male decides
the sex of the baby. 50 to 50 chance of having a male or
female
•Find the picture and glue it under the flap
Autosomes





Under the flap write
The other 22 pair of chromosomes
Carry information about everything else
except sex
Autosomal mutations are not passed to
offspring. Example skin cancer
Find picture cut it out and glue it under the
flap.
Sex linked disorders





Under the flap write:
Sex link traits are traits carried on the X
chromosome.
Males have a 50 percent chance of inheriting a sex
linked disorder. Females have a 25 percent chance.
Why?
Examples: color blindness, hemophilia, dunchee
muscular distrophy
Find the sex linked punnet square color it and cut it
out and glue it under the flap.
